Prof. Kyoung Sun Moon, Yale University, USA

Speech Title: Building Supertall in Asia and Middle East  

Abstract: Supported by rapid economic growth, major cities in Asia and the Middle East have been rising as new centers for tall and supertall buildings with their greater urban and global impacts. This presentation examines technological responses for building tall in Asian and Middle Eastern contexts. The architectural transformation and globalization of what was once called the American building type in Asian and Middle Eastern countries is studied. Sustainable design technology transfer and adjustment in Asian and Middle Eastern climates are also presented. Further, future prospects on supertall design in Asian and Middle Eastern contexts are discussed. Emphasis is placed on building supertall in China, considering its ever-increasing dramatic development of tall buildings in recent years.

Prof. C. W. Lim, City University of Hong Kong, Hong Kong

Speech title: A New Symplectic Approach for Thermal Buckling of Cylindrical Shells

 

Abstract: In the aftermath of 911, thousands of lives were sacrificed mainly due to the collapsed of two tall buildings resulted from excessive temperature that weakened the building structures.  In this aspect, we intend to study the effects of temperature on the possible collapse of building due to structural buckling.  Specifically, the research here deals with thermal buckling of cylindrical shells in a uniform temperature field based on the Hamiltonian principle in a symplectic space.  In the system, the buckling problem is reduced to an eigenvalue problem which corresponds to the critical temperatures and buckling modes.  Unlike the classical approach where a predetermined trial shape function satisfying the geometric boundary conditions is required at the outset, the symplectic eigenvalue approach is completely rational where solutions satisfying both geometric and natural boundary conditions are solved with complete reasoning.  The results reveal distinct axisymmetric buckling and non-axisymmetric buckling modes under thermal loads.  Besides, the influence for different boundary conditions is discussed.

Keynote Speaker III

Prof. Xiaohong Zhu, Sichuan University, China

Speech title: Graphene-based Electrode Materials for Supercapacitors

 

Abstract: Graphene has attracted much attention since it was firstly stripped from graphite by two physicists in 2004, and the supercapacitor based on graphene has obtained wide attention and much investment as well. However, there are many problems to solve in practical application of graphene-based supercapacitors, for instance, how to reduce the cost and simplify the fabrication process and how to improve further the electrochemical performance. In this talk, I will present our recent breakthroughs in fabricating graphene-based electrode materials for high-performance supercapacitors. First of all, to avoid graphene restacking, we come up with a pumping paper process, that is, when we use force to draw the paper from a small pore, the paper would fold. So here, we report a novel strategy to prepare wrinkled flower-like graphene through a simple suction filtration process. The wrinkled flower-like graphene shows a high specific capacitance of 272 F g-1 and a perfect capacitance retention of 99.5% after 2,000 times of charging/discharging cycles. Second, graphene/MnO2 and graphene/Ni(OH)2 composites with high electrochemical performance are prepared. Last but not least, 3D hierarchical porous carbon-based electrode materials (3DHPCs) with a composite structure are prepared from a biomass waste, sheep manure, by a facile carbonization and activation process without using any additional template. Benefiting from the composite structure, the ions experience a variety of environments, i.e., graphene-like sheets, nanotube- and microtube-like pores coexist in the same material, which, in turn, contribute significantly to the excellent electrochemical properties of supercapacitors, comprising high specific capacitance, outstanding rate capability and excellent long cycle stability. The specific capacitance at large current densities of 1 A g-1 and 50 A g-1 reaches as high as 486 F g-1 and 411 F g-1, respectively, in 6 M KOH electrolyte. Furthermore, the supercapacitor device based on 3DHPCs shows a superior cycle stability with almost 100% retention of the initial specific capacitance after 10,000 cycles; in addition, it yields a Ragone curve with high energy and power density combinations of 57.08 Wh kg-1 at 25.37 kW kg-1.

Prof. Chien-Yuan Chen, National Chiayi University, Taiwan

Speech title: Application of thermal images for determining the vegetation coverage ratio at free-frame shotcrete grid beam protected slope

 

Abstract: In this study, infrared thermography was used to determine the vegetation coverage ratio (VCR) at a free-frame shotcrete grid beam-protected slope. An infrared thermal imager can detect the changes in surface radiation temperature on naked and vegetation-covered slope areas. Regional temperature analysis was performed through thermography, and the average temperature derived from the captured thermal images was used as the index for the vegetation area; the VCR was also evaluated. This method can be used in engineering practice after construction to reduce the errors in subjective visual judgment and can also serve as an effective and scientific evaluation methodology. A long-distance noncontact detection method for VCR evaluation can increase the engineering applicability of the proposed method after construction.

Prof. Muthukumaran Packirisamy, CONCORDIA University, Canada

Speech Title: ADVANCED NANO COMPOSITE PLATFORMS: SYNTHESIS AND BIOLOGICAL APPLICATIONS INCLUDING CANCER DIAGNOSIS

Abstract: Nanometal-polymer composite films are hybrid materials with inorganic nanoparticles immobilized and uniformly dispersed into a polymer matrix. Nanoparticles such as gold and silver, used to enhance the optical properties of the polymers, are called `optically effective additives` as they lead to new functionalities of the polymer based materials. Au (Ag)-polymer and copolymer composite films are suitable for applications such as waveguides, color filters, thermo-chromic materials etc. The strong plasmon band of Au and Ag nanoparticles (Localized Surface Plasmon Resonance) in the visible spectrum, that originates from the excitation of plasmons by the incident light, makes noble metal-polymer nanocomposites particularly adequate for sensing and biosensing applications. Furthermore, association of Au and Ag nanoparticles of various shapes with poly(dimethyl siloxan) (PDMS), allows the use of nanocomposite materials for microfluidic biosensing as well. In this presentation, we will talk about the in-situ synthesis of Au-PDMS and Ag-PDMS nanocomposites both at the macroscale and inside the channel of a microfluidic chip. The in-situ synthesis of nanoparticles involves the reduction of gold ions in a gold precursor solution by the curing agent of the polymer. The kinetics of the reaction has been investigated and the effect of annealing temperature on the morphology of nanoparticles has been studied by using imaging and spectroscopic methods. The nanocomposite has been successfully used for sensing of antibody-antigen interactions, allowing the detection of various important proteins. Nanocomposies of metals integrated into other polymers such as PMMA, PVA, and PS have been synthesized as well by using UV, microwave and thermal reduction methods. The effect of the particle`s shape on the properties of nanocomposites and their sensing abilities has also been studied by synthesizing nanostar particles and integrating them into microchannels. Because of the biocompatibility and non-toxicity of gold and silver nanoparticles, their nanocomposites can be used for plasmonic detection of biological entities in cancer research.
